A massive "current of fire" on the sun has started running at high
speed, surprising researchers and challenging some models of the solar
cycle.

Determining the interior of the Sun,like that of the Earth is a
speculative endeavor *hence such an assertive pseudo-authoritative
'surprise' does nothing,at least not today.Unlike others here,I was
working with two large external rings surrounding a star with a
smaller intersecting ring back in 1990 or 4 years before they were
observationally discovered -

While it is the only copyright I ever took out *and really means
nothing other than I was working on the stellar geometry in terms of
natural efficiencies in 1990,it is now a private work ,something I
take a pride in working on when nobody else was and perhaps never will
even though it has been observed.

All rotating celestial bodies with viscous compositions display
latitudinal differential rotation or what amounts to the same thing -
an uneven rotational gradient between the maximum equatorial speed
down to polar latitudes as opposed to something like the Earth's
fractured crust which has an even rotational gradient with a maximum
equatorial speed of 1037.5 miles per hour.There is no reason to
believe that the Earth's viscous interior is exempt from differential
rotation,after all,it displays the expected spherical deviation of 40
km due to that uneven rotational gradient,stars of the same mass but
with different maximum rotational speeds display variations in
spherical deviation,the faster it spins the greater the spherical
deviation due to more differential rotation shear bands on a faster
spinning star .

In short,in order to investigate the consequences of differential
rotation,on a star or on the fractured surface crust of the
Earth,speculative notions of 'convection cells' as described in that
article have to be set aside, but with the global geographical feature
of the Mid Atlantic ridge requiring a global mechanism,the only
suitable candidate is the lag/advance mechanism inherent in
differential rotational shear bands and its tendency to generate
symmetrical crust either side of the Mid Atlantic ridge with special
note of the 'S' shape,the fracture zones running parallel with the
Earth rotational characteristics and other great clues linking
planetary dynamics to evolutionary geology.

Why set aside *'convection cells' in the earth? *Can't differential
rotation and convection cells be happening in the earth's interior at
the same time?http://en.wikipedia.org/wiki/Mantle_plume

* If you ever find a study which links the Earth's spherical
deviation

using
* differential rotation as the bridge between the uneven rotational

of
* the fractured surface crust then let me know.

"Global coupling at 660 km is proposed to explain plate tectonics and
the
generation of the earth’s magnetic field

Jozsef Garai

The presence of low viscosity layers in the mantle is supported by
line of geological and geophysical
observations. Recent high pressure and temperature investigations
indicated that partial carbonate melt
should exist at the bottom of the lithosphere and at 660 km. The
presence of few percent carbonate melt
reduces the viscosity by several order of magnitude. The globally
existing 660 km very low viscosity layer
allows the development of differential rotation between the upper and
lower mantle. This differential
rotation between the 660 km outer shell and the rest of the earth
offers a plausible explanation for plate
tectonics and for the generation of the earth’s magnetic field. Simple
dynamo model is proposed, which
able to reproduce all of the features of the contemporary and, within
reasonable uncertainty, the
paleomagnetic field. The model is also consistent with geological and
geophysical observations."
